MACHINE FOR PRESENTING LIQUID OR VIS COUS MATERIAL.

Patented July 6, 1915.

7 Serial No. 551,556. I

To all whom it may concern:

Be it known that I, FREDERICK M. FUR- BER, a citizen of thevUnitedStates, residing at Revere, in the county of Suffolk and State ofMassachusetts, have invented certain Improvements in Machines forPresenting Liquid or Viscous Material, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters indicating like parts theseveral figures.

This invention relates to machines for presenting liquid or viscousmaterial in position to be applied to stock and is herein shown asembodied. in a machine designed for presenting shellac or similarmaterial in position to be applied to such stock as toe stiffeningmaterial of a shoe upper. This stiffening material comprises superposedlayers of fabric or leather, the adjacent faces of which are to becoated with shellac which is absorbed more or less by the fabric orleather and when it dries sticks the layers together and stiffens themso that they retain the shape of the last orform over which they havebeen laid to dry. The shellacking operation is usually performed inconnection with the assembling, pulling over, and lasting operationswhich follow one another at short intervals so that the shellackedfabrics forming part of the shoe upper materials are incorporated in thelasted shoe before the shellac has time to dry or set and thus the toestiffener takes the shape of the toe portion of the last. Liquid shellacevaporates rapidly so that it is necessary to avoid exposure of theshellac to the air as much as practicable.

WVith these conditions in view the present invention has for its objectto provide an apparatus by which a charge containing a proper quantityof shellac for coating one shoe stiffener can be withdrawn from aresformed and arranged to be moved into a on the drawings will beabsorbed by the reservoir. of shellacand Withdrawn carrymg a.substantially uniform charge of shellac properly distributed over itssurface so that when the stock to be stiffened is laid against thesurface of the presenter it will be coated to a predetermined extent.

Other features of this invention include novel means for actuating thepresenter and 3 of parts and more important details of con-' struction,will be definitely pointed out in the claims at the end of thedescription.

eferring now to theaccompanying drawings:-Figure 1 is'a' perspective ofthe machine with the presenter in the reservoir. Fig. 2 is a perspectiveof the machine with the presenter withdrawn from the reservoir. In this.figure certain parts of the machine which are shown in ,Fig. 1 have beenomitted. Fig.3 is a vertical crosssection of the shellac reservoir and.Fig. 4 is a per spective in detail of the divided driving shaft and thelatch, the parts of said shaft being in position to cause said shaft tobe rotated.

Referring now to the accompanying drawings, the machine comprises astandard 1 which carries a reservoir 3 having a storage compartment 5and .a loading compartment 7. This loading compartment is closed exceptfor a port 79 and a slot 9 in its top wall which is designed to receivea presenter 11, said presenter being shown in said compartment in Figs.1 and 3 and in its delivery position in Fig. 2. This presenter is aplate having substantially the contour of the portion of stock which isto be coated with shellac. The side faces of the presenter are providedwith horizontal ribs spaced a substantial distance apart to formhorizontal grooves into which the shellac will enter when the presenteris submerged in the reservoir and from which the shellac stock pressedagainst the sides of the presenter.

In the drawings, both sides of the presenter are ribbed, as described,in order to coat similarly the adjacent faces of two pieces of stock. Ifit is desired to coat only one surface of stock, one side only of thepresenter will be formed as described for carrying shellac. Thearrangement of horizontal ribs is of particular advantage in enablingthe presenter to take up and carry in a uniformly distributed conditionsuch fluid material as shellac which would flow freely out of merepockets or depressions in a roughened surface. The ribs Which arerectangular in cross section form dams extending entirely across thepresenter and offering no opportunity for the shellac to flow downwardlyat any special point.

The presenter is vertically adjustable on a support 15 to which it isfastened by a bolt 13. In order to cause the presenter 11 to be movedfrom loading to delivering position without being tilted the support orlink 15 is pivoted at 17 and 19 to cranks 21 and 23. The crank 23 isfast to a shaft 25 rotatable in a bearing 29 which is shown as integralwith the reservoir. A collar 27 is fixed upon the shaft 25, and a coiledspring 31 which has one end fast to the collar 27 and the other end fastto the bearing 29 tends to hold the crank 23 normally in the positionshown in Fig. 1, a stop 33 on said crank being arranged to cooperatewith a lug 35 to limit the motion of said crank. The crank 21 is fast toa divided shaft 37, the parts of which will be designated forconvenience the power end and the crank end. This shaft is rotatablymounted in bearings 39 and 41 and has fast to it two collars 43 and 45there being a coiled spring 47 located between the collar 45 and thebearing 39, said spring tending to cause relative longitudinal movementbetween the parts of said divided shaft 37. Fast to the extremity of thepower end of the shaft 37 is a member 49 carrying a friction disk 51which cooperates with a similar disk 53 fast to a driving pulley 55,said pulley being freely rotatable on the shaft 37 when the parts are inthe position shown in Fig. 1 and being adapted to be clutched to saidshaft when the disks 51 and 53 are pressed together.

Turning now to Fig. 4, it will be seen that the adjacent ends of theparts of the shaft 37 have flat faces which overlap so that whilerelative longitudinal movement between the parts is permitted, relativerotation is prevented. In order to limit the movement of the parts ofthe shaft toward each other, a stop 54 is provided on the crank endwhich cooperates with a shoulder formed on the power end. As has beenstated, the spring 47 tends to separate the parts of the shaft andthereby to separate the friction disks 51 and 53 so as to permit freerotation of the pulley 55. In order, however, to cause said pulley to beclutched to the shaft when desired, a latch 57 normally held as shown inFig. 1 by a spring 58 is pivoted to the reservoir at 59 and a chainattached to its lower end passes over a roller 63 and is connected withany suitable treadle 64. When the treadle is depressed the collar 45 andwith it the power end of the shaft is forced toward the crank endthereby clutching the pulley 55 to said shaft. Inasmuch, however, asonly a partial rotation of the shaft is desired in order to bring thepresenter into the position shown in Fig. 2 a notch 65 is formed in thecollar 45 which, when the shaft has moved through 180, arrives oppositethe projection 67 upon the latch whereupon the spring 47 moves the powerend of the shaft away from the crank end and thereby disengages thepulley At the same time, the flat bottom face of the projection 67engages the fiat radial face of the notch 65 and prevents the shaft frombeing rotated in the opposite direction by the spring 31. The presenteris consequently held in the position shown in Fig. 2 so that theoperator may wipe the shellac from its sides. In order to insure thatthe rotation of the shaft 37 shall cease at the end of 180 a stop 69 onthe crank 21 is arranged to contact with a fixed lug 71. \Vhen thetreadle is released the spring 53 pulls the latch to the position shownin Fig. 1 whereupon the shaft 25 under the influence of the spring 31becomes a driving shaft and returns the presenter to the loadingcompartment of the reservoir as shown in Fig. 1.

Vith the construction thus far described, it might happen that when thecranks 21 and 23 reached dead center the link 15 might move angular-1y,that is, while the crank 21 went forward the crank 23 might go backward.In order to obviate the possibility of such a movement of the parts, a

third crank 73 journaled on a stud 75 is pivoted to an extension of thelink 15 at 77, the effect of this construction being to prevent anyangular movement of the link 15 and to maintain the pivot 17 at alltimes vertically above the pivot 19, it being understood that the cranks21, 23 and 73 .re all of the same length.

Turning now tr Fig. 3, a port 7 9 connects the compartment 5 of thereservoir with the loading compartment 7, valve 81 mounted on a stem 83being provided for controlling said port. The stem of the valve isthreaded through a bore in the lower part of the reservoir so that byrotating said stem the port 79 may be opened or closed. An air passage85 leads from the upper portion of the compartment 5 and terminates in ation disks 51 and 53 to be separated part of the reservoir is a fillingtube 95 provided with a loosely fitting cover 97. With this reservoirthe surface of the liquid in the loading compartment will lie in a planepass- 7 ing through the uppermost point of the port 79 irrespective ofthe level of the liquid in the storage compartment 5 provided the liquidin this compartment extends above the port 79. When it is desired toreplenish the supply, the handhold 89 is rotated to close the port 79and open the air passage 85. The cap 97 is then removed and the shellacor'other liquid is poured into the filling tube. The advantages of thisconstruction are that the opening in the top of the reservoir need notbe air tight and that the reservoir may be filled at any time withoutinterrupting the operation of the machine. 4

The operation of the machine is as follows: The treadle is depressedthereby rocking the latch on its pivot and bringing the friction disks51 and 53 into contact. This causes the pulley 55 to be clutched to theshaft 37 whereupon the crank 21 moves angularly until the notch permitsthe fricforce of the spring 47. The mechanism is thus brought to theposition shown in Fig.2. The operator then applies the material to thepresenter and wipes off the shellac upon it after which he releases thetreadle. The spring 58 then withdraws the latch from the notch 65, andthe spring 31 causes the presenter to be moved back into the loadingcompartment as shown in Fig. 1.
